Welcome I am new herein also. I collect only graded materials such as slabbed coins and encapsulated banknotes since I lack the skills to grade coins or banknotes myself.
I live in a modern city but lack the ability / connections to learn to grade stuff since I lack other collectors me.
Thus I buy graded so I can prove its authentic and graded impartially by the TPG PCGS
/ Anacs / NGC
I only buy from the four top tier grading companies thus my collection is protected and proven.
I only buy gold coins graded 70 ( worldwide ) in 1/10 to 1/4 oz .9999 gold and banknotes graded 67-70 , but usually settle for a 68 grading...
The State Quarters
were/ are almost the best only eclipsed by the national parks and animals ! ! !
I never buy silver since it is always going to tarnish and develop milk spots , and platinum; it just looks like grey silver.
Truly short or long term nothing beats gold for looks and appeal , the best sizes are 1/10 and 1/4 ounce; I have moved into the quarter ounce as my selling later strategy will be as "artwork".
The size and detail and eye appeal of gem perfect 70 1/4 oz pure gold is sure to find some willing buyers ! ! !
Remember quality holds its value far more than quantity and hope you enjoy your collecting hunts :)
